The 3-lug mount is a quick-detach suppressor mounting system used with hosts equipped with a 3-lug barrel — most commonly found on HK MP5, SP5, MP5K, and similar 9mm host firearms that use a Nielsen-device-based suppressor attachment. The 3-lug mount threads onto the host firearm’s barrel stub and the compatible suppressor locks onto the mount via three evenly spaced lugs on the suppressor’s mounting hub, allowing the suppressor to be attached and detached in a single rotation without tools. The locking mechanism provides a secure, repeatable attachment that returns the suppressor to the same indexed position each time it is installed, ensuring consistent point of impact shift and reliable lockup. 3-lug mounts are model-specific to the Rugged Suppressors Obsidian 9 and are not interchangeable with other suppressor mounting systems. Confirm that your host firearm uses a 3-lug barrel compatible with this mount before ordering. The mount must be installed and properly timed on the barrel before the suppressor can be attached. Refer to Rugged Suppressors installation instructions for proper installation and torque specifications.

Frequently Asked Questions
What host firearms use a 3-lug barrel?
3-lug barrels are most commonly found on HK MP5, SP5, MP5K, and similar pistol-caliber firearms. The 3-lug system is an HK-pattern interface — confirm your host firearm has a 3-lug barrel before ordering this mount.
Is this compatible with all Rugged Suppressors?
No — the 3-lug mount is specific to the Rugged Suppressors Obsidian 9 suppressor. It is not compatible with other Rugged Suppressors models or with suppressors from other manufacturers without verifying the mounting interface.
Does the suppressor stay on the mount during firing?
